Campaign Mode strategy: When starting the game, you may want to focus your troops on the intersection in the given map. Make sure fee is safe on the grass side to avoid having her killed from the enemy wave.
For this level, we found out that 1 barracks and Lancelot are good enough to control the incoming crowd. The three other sites in the intersection were filled with cannons to obliterate the congestion happening there. Keep summoning Fee’s wolf to add in to your troops. Fully upgrade cannons to have the rockets with maximum reach in the map.
This should keep your villager safe on the 5th wave. Fully upgrade your barracks to render better stats to your troops. Finally, add some fully upgraded archer towers to trim down the incoming horde in the final leg of the level.
Legendary strategy: Barracks with wizard tower’s haste buff is all you need in this one. Put them at the intersection along with an archery tower and your Heroes, and you’re good to go. Keep your ranged heroes out of harm’s way but in proximity and you’ll finish up in no time.
